Abstract
To evaluate serum markers for the diagnosis ofCandida pyelonephritis, levels of D-arabinitol, candidal mannan antigen and candidal protein antigen were measured using an enzymatic fluorometric assay, an enzyme immunoassay and a latex agglutination assay, respectively. The study group comprised 36 patients with candiduria (11 disseminated candidiasis, 9Candida pyelonephritis and 16 colonization) and 27 without candiduria. The D-arabinitol/creatinine ratio was the only marker that differentiated betweenCandida pyelonephritis and colonization (p<0.01). Using the cut-off values (1.4 µmol/mg of D-arabinitol/creatinine ratio, 0.28 of mannan/creatinine ratio (×104) and 1:4 of protein antigen titer) D-arabinitol/creatinine ratio showed the highest sensitivity inCandida pyelonephritis (77.8 %) as compared to mannan/creatinine ratio (55.6 %) and protein antigen titer (11.1 %) although there were no differences in specificity, positive predictive value or negative predictive value. These results suggest that D-arabinitol/creatinine ratio is the most useful marker ofCandida pyelonephritis.
